Time Series/Sequence Clustering

Section below prepare each swing current data from final_PCM_data table into time series object in order to apply time series clustering algorithm based on Euclidean distance. As part of clustering output we get a matrix with pair-wise dissimilarity score for each of the swing current profile. We took the mean score for each of the swing’s dissimilarity score compared with all the rest of the swing as an indicative score of how (dis)similar a swing is compared to rest of the swings. In general, lower the mean dissimilarity score of a swing, the more similar that swing profile is to majority of the swings.
